Describe what would happen to the column of mercury in the following manometers when the stopcock is opened.

Pressure $P$ is a function of mercury level height $h$ according to\[P=\rho g h\]where $\rho$ is the density of liquid mercury, $g$ is the acceleration due to gravity. since $\rho$ and $g$ are constant, pressure can be expressed in terms of the height of mercury (mmHg). In fact, a normal atmospheric pressure corresponds to a rise of $760 \mathrm{mm}$ in mercury level. Thus, we can write\[1 \mathrm{atm}=760 \mathrm{mmHg}\]

In physics, a gas is one of the three major states of matter (the others being liquid and solid). A gas is a fluid that does not support tensile stress, meaning that it is compressible. The word gas is a neologism first used by the early 17th-century Flemish chemist J.B. van Helmont, based on the Greek word ("chaos"), the simplest of all the elemental forms of matter.

In physics, thermodynamics is the science of energy and its transformations. The three laws of thermodynamics state that energy can be exchanged between physical systems as heat and work; that the total energy of a system can be calculated by adding up all forms of energy in the system; that energy spontaneously flows from being localized to becoming dispersed, spread out, or uniform; and that the entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.

So this question is asking what happened to the column of Mercury in the following Manama eaters when the stock office opened? Let's look at the first cape. The the stopped cars right here. Once in open, um, is that the pressure will drop right so the pressure would drop. It means that the miracle moving this side so the heights will decrease. Okay, so look at this one have to stop. What if the stop cock is open right here? All the vacuum space will fill by D. I am a historic pressures, so the pressure will press down the mercury, so the heights will also dropped.
